Commit97b388d70b("io_uring: handle completions in the core") moved the error handling from handler to core. But for io_uring_cmd handler we end up completing more than once (both in handler and in core) leading to use_after_free. Change io_uring_cmd handler to avoid calling io_uring_cmd_done in case of error.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
